Answer 1

You shouldn't execute a SELECT with an ExecuteNonQuery(). It is called ExecuteNonQuery because you want something to execute that is not a query. A SELECT is a query. You want to ExecuteReader. If you want to do an UPDATE or DELETE, then you can do an ExecuteNonQuery() and that will show how many rows were affected.
